How does green investment, financial inclusion, and digitalization drive environmental sustainability in China? A perspective based on quantile-on-quantile regression and wavelet coherence analysis

This research delves into the potential for promoting environmental sustainability in China through an in-depth analysis of the interplay between green investment, financial inclusion, digitalization, and their impact on sustainable development. The study adopts a novel three-stage methodology that encompasses quantile-on-quantile regression, Granger causality in quantiles, wavelet analysis, and robustness tests to ensure the reliability of the findings. The results uncover a robust and positive relationship between green investment, financial inclusion, digitalization, and environmental sustainability in China. These findings underline the significance of directing investments towards green resources, fostering technological innovation, and strengthening the financial sector to facilitate the country's transition towards sustainable development. Importantly, the study emphasizes the critical role played by green investment, financial inclusion, and digitalization in enhancing the environmental sustainability of China's current economic growth trajectory. By providing valuable insights, this research becomes a valuable resource for developing countries striving to achieve their sustainable development goals through the strategic utilization of technology innovation, green investment, and financial inclusion.
